Advanced CheckpointingMany coins in the altcoin space are susceptible to the infamous 51% attack. Even Bitcoin is only protected by it's high hash rate.In contrast advanced checkpointing provides an effective protection against 51% attacks independent of the hash rate of the coin.The technology was introduced by Peercoin and adapted for the Luckycoin in November 2013. Instead of manual checkpoints that require a client update, advanced checkpointing automatically synchronizes checkpoints over the network at a predefined depth of the block chain. The checkpointing system allows the block chain to resolve small forks on it's own without intervention, but enforces consensus if two different chains grow too large.

Block Rate LimiterThe block rate limiter was introduced first in December 2013 by the Luckycoin to fight abusive multipool mining and prevent attacks on the block chain that result in an unusually high block rates. The technology introduces a new network rule that allows only a maximum of six blocks to be mined within a time span of 90 seconds. Additional blocks within the 90 seconds window are rejected. This makes flash mining the Luckycoin uneconomical.

OpenSSL HeartbleedThe serious OpenSSL Heartbleed bug was fixed in the latest Luckycoin v1.0.1 release. The Windows LuckycoinQT wallet is now compiled with the latest OpenSSL 1.0.1g release that fixes the bug.

Coin Distribution and InflationThe Luckycoin implements an accelerated reward reduction scheme. The block reward halves once every 100,000 blocks. Over the last year nearly 75% of all coins have been distributed via mining. The current coin production per day is worth about $100-$200 that has to be absorbed by the exchanges.

bootstrap.dat allows a new Luckycoin client (not synced) to rapidly import the initial blocks from a local file instead of slowly downloading blocks from random peers. This significantly reduces the time it takes to get a client synced with the current blockchain.

Simply having bootstrap.dat in Luckycoin's expected data directory will make your initial block sync much faster. The import process can be even faster if you use the -dbcache=1000 command line parameter which uses an additional 1GB of RAM for the database index cache.

Extracting the bootstrap.dat.xz

Regardless of your operating system, use the following steps to make use of the bootstrap.dat file:

1. Download bootstrap.dat.xz from mirrors or torrent.2. Decompress the bootstrap.dat.3. Put it into the Luckycoin datadir. "%appdata%/luckycoin" / "~/.luckycoin" (This is the same folder that contains wallet.dat and the blocks folder.)4. Delete bootstrap.dat.old if you want to recover some storage space.

Luckycoin Data Folder

Linux

Code:

xz -d bootstrap.dat.xz

Luckycoin's data directory is located in ~/.luckycoin/ by default. You can run ls -a to see directories that start with a period. You can also search for the directory with the following command:

Code:

find / -name wallet.dat -print 2>/dev/null

MacYou can obtain xz from MacPorts or http://macpkg.sourceforge.net/. luckycoin's data directory should be located in ~/Library/Application Support/luckycoin/.

Windows7Zip is a free utility that can decompress .xz files, so does the latest version of WinRAR.

Click on Start then Run (or press WinKey+R) and type:

Code:

explorer %APPDATA%\luckycoin

luckycoin's data directory will open. "AppData" and "Application Data" are hidden by default in Windows.

Copy bootstrap.dat to data directory

Copy the bootstrap.dat to your data directory. Load the luckycoin client and wait for it to load the blocks. After loading is complete, the bootstrap.dat will be renamed to bootstrap.dat.old at which point you can choose to delete it.

Yea, our baby has grown up quite a bit. The 1st anniversary is in about a month on May 22.

We are already close to the 2nd block reward reduction to 22 LKY at block 200,000. Please join the miners at pool.luckycoin.cc!

Hello Guys, I just want to let you know, that I am buing LKY as much as I can. This coin is awesome, with active developer, unique, just lacks broader popularity. It will take some time, but this coin is already old and not pump&dump scam, it is like a gold for me. Thank you Titan.

Thanks!

I've been working on a better difficulty retargeting scheme over the last few weeks with an intra block retargeting algorithm to make the network more resilient.

Titan, I like what you are doing for LKY!!! I am promotiing LKY on Cryptsy, this coin is awesome and need to have much bigger community. This is not pump&dump scam but serious coin!! I think LKY will increase the price 50x next year.

Great! Yes, there is a lot of room to grow. We have a stable investor base and already a relatively low inflation.The network operation is very close to the optimal block rate since the last reward reduction and we are already 25% through the 3rd reward reduction cycle.
